WILLIAM HENRY JAY, OF MOBBIDG-E, SOUTH DAKOTA.

Application filed September 21, 1922.

To all whom it may concern:

Be it known that I, Vi ILm M HENRY JAY, a citizen of the United States, and a resident of Mobridge, in the county of Walworth and State of South Dakota, have invented certain new and useful Improvements in Combination Locks, of which the following is a specification.

My present invention relates generally to con'ibination locks. and more particularly to that type of combination lock described and claimed in my Patent 1,313,536 dated August 19, 1919, my primary object being the provision of certain improvements and re finements in my patented device which will render the same more practical, more durable, more pleasing in appearance and prac tically proof against unwarranted manipulation, and a furtherohject consists in the provision of certain additions to my patented lock which will be better understood and appreciated from the following description in connection with the accompanying drawings.

controlling arm or pointer of the outer disc and its associated washers.

Figure 18 is a detail perspective view of the associated parts upon the outer or exposed end of the disc supporting stem, including the controlling arm or pointer of the inner disc.

Figure 19 is a detailed perspective view of one end of the bolt-throwing shaft with its member adapted to receive the direct actuating key.

*igure 20 is a detailed perspective view of the connecting bar and its hinged key. Figure 21 is a detailed perspective view of the housing and supporting member of the connecting bar of Figure 20.

Referring now to these figures and as in my patent above referred to, a connecting bar 25 is shiftable axially into and out of endwise engagement with the bolt-throwing shaft 25 of a door or other lock, plainly indicated in Figure 2, its connecting bar 25 having at its outer end a hinged key 26 and having at its inner end a slot 27 adapted to receive therein the extremity of a reduced extension 28 of the bolt-throwing shaft 25% Also like my patented device inward move meut of the connecting bar 25 to operatively engage the bolt-throwing shaft 25 is normally prevented by virtue of the fixed position of a pair of permutation discs, includ ing an inner disc 29 and an outer disc 30, the lower portions of whose peripheries extend between the normally spacedadjacent ends of the connecting bar 25 and the boltthrowing shaft 25.

According to my present improvements, the lock as a whole is mounted in connec tion with a cylindrical casing 31 adapted by virtue of its surrounding flange 31*, to seat in telescoping relation upon a circular supporting plate 32, the latter of which may be secured to a door 33 or other part to be locked, as for instance by screws 34 shown in Figure 5, which are concealed by the easing 31 when the latter is in place. For the connection of the casing 31 around the supporting plate 32, this supporting plate may have an opening 35 (seen in Figure 5) through which a screw 36, extending through the door 33 as shown in Figure 2, may be screwed into a threaded socket 37 of the easing 31, the latter having at one point a notch 38 in its flange 32, as seen in Figure 7, which by virtue of its reception of a pin 39 of the supporting plate 32 thereafter looks the casing 31 against rotative displacement with respect to the supporting plate 32.

The connecting bar works through an opening in the front wall of the casing 31 and is mounted within a supporting thimble shown particularly in Figures 2 and 21, slotted as at 41 so that the key 26 may drop when the connecting bolt is in its normal outer position. This bar 25 has an interme diate annular shoulder 42 against which the outer end of a spring 43 engages. The 1nner end of this spring, which is housed by the thimble 40, bears against the front wall of the casing 31 so that to shift the connectin bar 25 inwardly into engagement with the bolt-throwing shaft 25 it is obviously necessary to first swing the key upwardly upon its hinged connection with the bar 25 and then thrust the bar and key inwardly against the tension of spring 43 which at the end of the operation and upon release of the key shifts the connecting bar outwardly to the normal inactive position of Figure 2. 1

The permutation discs 29 and 30 are mounted on a sleeve 44 shown particularly in Figure 11, which sleeve is rotatably mounted upon a stem 45 and extends through and is rotatable within a second sleeve 46, the latter of which is ournaled through the front wall of the casing 31 above the bar housing thimble 40. The stem 45 has at its inner end a squared projection 47 disposed in a similarly shaped aperture centrally of the supporting plate so that the stem 45 is thus prevented from rotation, its outer threaded end 48 projecting beyond the front wall of the casing 31 and through and beyond the sleeves 44 and 46-, for the reception of a washer 49 and a clamping nut 50, outwardly beyond a supporting plate 51, through the aperture 52 of which the threaded end 48 of the stem projects. This supporting plate has a lower ring-shaped portion 53 which surrounds the bar supporting thimble 40, and the supporting plate 51 is firml I held in place by screws 54 which are threat ed into the same upon diametri- (ally opposite sides of its lower ring-shaped portion, from the inner side of the front wall of the casing 31. The adjusting nut engages the threaded end of the stem 45 within an adjusting nut housing 55 securely fastened to the supporting plate 51 by a screw 56 so that in the ordinary manipula tion of the clamping nut 50 a key 57 (shown in Figure 18) is necessary for the release or tightening of the clamping nut 50.

Between the permutation discs 29 and 30 is disposed a bearing ring 58 having balls 59 so that the discs may thus be freely rotated with respectto one another, and these discs are actuated respectively by flanges 59 and 60upon the inner ends of the sleeves and 46, flange 59 having its forward face roughened as by means of radial serrations shown in Figure 11 to engage the similarly serrated central portion of the rear face of the disc, 29 and flange 60 of sleeve 46 having its rear face similarly roughened for engagement with the central roughened portion of the front face of disc 30, the latter of which has a single connecting bar receiving aperture 61, which upon rotation of the disc may be alined with the connecting bar 25. This disc 30 is rotatable within a circular shield 62 shown in Figure 15 and having a series of apertures 63 therearound forwardly of the forward disc 30, and which shield is rotatable so that any one of its apertures 63 may be alined with the aperture 61 of disc 30 as hereinafter described.

The inner or rear disc 29 has but a single opening 64 providing for the passage of the connecting bar 25 therethrough and this disc is secured within the flange 65 of the shield 62 so as to rotate with the shield, its aperture 64 being alined with one of the apertures 63 of the shield. In alinement with the other apertures 68 of the series of apertures with which the shield is provided, the inner or rear disc 29 has a series of circular recesses 66 for a purpose which will be presently described. This disc 29 also has peripheral notches 67 at diametrically opposite points which are engaged by inner projections 68 of the flange 65 of the shield, the shield having bent tongues 69 which prevent shifting of the disc 29 in a rearward direction.

It will also be noted that the stem 45 has a flange 70 rearwardly beyond the rearmost disc actuating flange 59, the latter of which is a part of tie sleeve, 44, the forward end of which sleeve has reduced lengthwise;

tongues 71 extending into recesses 72 of its respective controlling arm or pointer 73, the latter of which extends radially of the easing- 31 and upon its external surface so as to cooperate with the dial, stan'iped, printed or otherwise impressed upon the outer surface of the front wall of the casing. Likewise the sleeve 46 has endwise projectingtongnes 74 at its forward or outer end which si1ni larly extend into recesses 75 of its controlling arm or pointer 76, the latter like the pointer 73 extending over the dial of the casing.

The pointer 76 by means of which the outer sleeve 46 and the outer or forward disc 30 are rotated, is disposed between a washer 77 and a separator 78, while the pointer 7 3 by means of which the inner sleeve 44 and consequently the inner or rear disc 29 and shield 62 are rotated, is disposed between the separator 78 and a second separator 7 9, these separators 78 and 79 having notched lower portions 80 through which one of the screws 54 holding the frame 51 is extended as seen in Figures 2 and 6 in order to prevent rotation of the separators.

It is quite obvious that with the clamping nut 50 tightened to an extent necessary to draw the actuating flanges 59 and 60 into effective engagement with the roughened portions of the discs 29 and 30, swinging movement of the pointers 73 and 76 around the dial of the casing within the limits of their movement, serves to rotate the discs 29 and 30, during which rotation their openings 61 and 64 will be alined with the bolt-throwing shaft 25 and the connecting bar 25, as indicatedin Figure 2, it being only necessary for this purpose that the operator note the particular points on the dial at which the pointers should be brought to rest. /Vhen the discs have thus beenpositioned with their apertures in registry with the connecting bar 25 the latter can be pressed inwardly to engage the bolt-throwing shaft 25 as previously described, and by turning the key 26 the bolt-throwing shaft 25 will thus be rotated as desired. When this operation has been accomplished and the key 26 released with the result that and the latter then rotated by its pointer 7 6 until the connecting bar could be thrust through the disc aperture 61. VVith the shield 62 as provided by my present improvements, such unwarranted manipulation is prevented from being successful, the provision of this shield with a series of openings preventing any one from feeling their way through the shield and then through the disc 30 with any assurance of striking the aperture 64 of the inner or rear disc 29. Should an unwarrantedoperator succeed in passing the connecting bar through one of the apertures 63 of the shield and then through the aperture 61 of the outer or forward disc 30, it is obviously impossible that the inner or rear disc 29 be then rotated in feeling for the aperture 64, particularly in view of the fact that upon receiving the connecting bar into one of the recesses 66, rotation of the inner disc would be prevented.

In order to change the combination, the discs are first turned to the proper position as shown in Figure 2 and the connecting bar 25 received through the same so as to prevent their rotation. The key 57 is then utilized and passed into the clamping nut housing to engage the clamping nut 50. By this means the clamping nut may be loosened and the normally effective grip between the disc actuating flanges 59 and and the two permutation discs may be relieved. Then by grasping and shifting the pointer 73 to the desired new combination and thereafter re-tightening the clamping nut 50 before withdrawing the connecting bar, it is obvious that the change of combination will be complete.

Where it is desired that certain persons at least be allowed to quickly actuate the boltthrowing shaft 25 without delay incident to the manipulation of the combination features, I propose that the bolt-throwing shaft 25*" be provided with an arm 81 depending within the casing 31 and provided with a slotted lower end 82, the slot of which is adapted to receive the flat blade 83 of a key 84 shown in Figure 8 which may swing within an arcuate slot 85 in the lower portion of the'flange 31 of the casing 31 and whoseblade 83 may be shifted inwardly of the casing through a notch 86 centrally between the ends of the arcuate slot 85. The key introducing notch 86 is normally guarded, however, by a guarddisc 87 lying against the inner surface of the flange 31 of the casing, having a plurality of peripheral recesses, one only of which is of suflicient depth to expose the notch 86 for the introduction of the key 84. This guard disc 87 which is shown in Figures 2, 3 and 7 in particular is secured upon the inner end of a stud 88 whose outer portion is flattened so that it will in one position receive thereover a pivoted latch 89 in order to hold the stud 88 against rotation. This latch is piv-- oted to the flange 31. of the casing and is of curved form to lie between the external surface of the flange and a supporting plate 90 secured in spaced relation along the adjacent portionof the casing flange as seen in Figure The outer end of the stud 88 also has a threaded bore 91 as seen particularly in Figure 9 and with this bore the threaded extension 92 of the guard actuating key 93. may be associated so as to per-- mit the stud 88 to be rotated, after the pivotal latch 89 is released, in order that the single recess of the guard disc 87 may be alined with the notch 86 as shown in Figure 7 for the introduction of the key 84 by means of which direct actuation of the boltthrowing shaft 25 is contemplated.

It is obvious from the foregoing that my present improvements bring about an arrangement of parts adapting this particular type of permutation lock to a variety of uses and that they render the lock practically free from danger of unwarranted manipulation or release, and it is also obvious that my present improvements add materially to the effectiveness of my patented lock first above mentioned in respect to appearance, strength, durability and general effectiveness.
